Digital Multimeter:
A digital multimeter is also known as DMM. In today’s world, it is the most common items that are used as a test equipment in the electronics industry.There are so many test equipment items in the market, but we use the multimeters to get the excellent readings of the basic measurements in the terms of ohms, volts, and amps. Digital and logic technology are used by digital multimeters.
In other words, these devices use the integrated circuit (IC), in the place of analog techniques. In this design also many new test features are enabled to be embedded. By using the same multimeter you can make many other additional measurements.
Advantages of Digital Multimeters:
- Digital multimeter is free from wear and shock failures.
- Portable size makes it easy to carry anywhere.
- The reading speed is increased as it is easier to read.
- They are more accurate than analog multimeters.
- They cause less meter loading effect on the circuits being tested.
- They have a very high input impedance.
- They reduce reading and interpolation errors.
- Unlike analog multimeters, zero adjustment is not required.
Disadvantages of Digital Multimeters:
- When the battery is low, the display will be dim, and makes it difficult to read.
- It can record an error, in case of fluctuations or transients.
- If the voltage is increased beyond the limit, the meter will be damaged.
- Because of the digital nature, it is unsuitable for peaking tunable responses or adjusting tuning circuits.
- They are expensive due to high manufacturing cost.
We are also manufacturer and supplier of Digital Multimeter. We are manufacturers of Physics Lab Instruments in 30 worldwide countries.
